GuDViN [60]

<u>Explanation:</u>

s = ?           u = 0m/s        v = ?         a = 5m/s²        t = 2s

v = u + at                  

  = 0 + (5 x 2)              

  = 10 m/s                    

s = ut + 1/2 at²

= (0)(2) +  x    \frac{1}{2}  x 5 x 2²

= 10 m

Hope this helps!

Presence of _______- in retina gives us night vision that is help us to see in dim light.Required to answer. Single choice. Imme
qwelly [4]

Answer: Rods

Explanation:

The rod cells in the retina are the reason we are able to see at night and in dim light. They exist on the edges of the retina which is why they are also very useful for the peripheral vision of a human.

Rod cells number over 90 million in the eyes and although very useful for seeing in dimmer light, they are not very useful for color vision which is why humans see less colors in the dark.

A steel ball and a wooden ball of the same diameter are released together from the top of a tower. In the absence of air resista
ella [17]

Answer:

False

Explanation:

The steel ball and the wooden ball do not have the same force acting on them because their masses are different. But, they have the same acceleration which is the acceleration due to gravity g = 9.8 m/s².

Using the equation of motion under freefall, s = ut +1/2gt². Since u = 0,

s = 1/2gt² ⇒ t = √(2s/g)

Since. s = height is the same for both objects, they land at the same time neglecting air resistance.
